Theory of Machine A rotor which is balanced statically but not dynamically is supported on two bearings L apart and at high speed of the rotor, reaction on the left bearing is R. The right side of the bearing is shifted to a new position 2L apart from the left bearing. At the same rotor speed, dynamic reaction on the left bearing in the new arrangement will Become equal to R/4 Become equal to 2R Remain same as before Become equal to R/2 Become equal to R/4 Become equal to 2R Remain same as before Become equal to R/2 ANSWER DOWNLOAD EXAMIANS APP
